Provide Utility-API to access task

[GoogleCodeExporter]

In case a task comprises of subtasks there should be some utility function to 
iterate the subtask's data-folder to access their content.
At the moment this information is only provided in a txt-file and the user 
would have to parse it every time anew if this information is needed.

I'm not sure yet where this would best go:

1) a utility method getSubtasks(String contextId, storageService)
2) a method in TaskContextMetadata (no access to the storage service, so would 
need to be initialized externally)
3) a method in TaskContext (access to the storage service)
4) a method in the storage service getSubtasks(String contextId)

Any preference anybody (at least before I think harder about this)? ;)
